CONTAINER FOR'FLUIDI Application area Ianuary -25,'1927,"Sc11ia1 No. 168;47.2;and in Germany February 9,1926;

containers int'which' the depth of the fluid is automatically controlled are-known' The known constructional form-s provide-wlthma main container *orb'eside'a main container in 5 conjunction-therewith'an 'accesseryreceptacle.

The fluid is allowed 'to'fl'ow through an open ing extending on the bottom of the container into the receptacle in the same proportion as theairmayenter tlfesaid opening. All those Th'eGpresen-t invention relateseto a container of utm-ostsim-pl construction which. removes all drawbacks abovere-fc'rrcd to, and pro vides" adouble: closure; in connection with bottles,flasks and vesselsof any desired shape adapted tereceive gl-ue,ink, color or the like.

Reference is made to' the'--' accompanyingdrawing; in iwhich a constructional J formof the inventionis'showmby way' of example. The container on preferably made of pressglass has a somewhat conically formed neck d. A glass tube b is arranged in the container a. be shaped somewhat conically and may be detachably secured to the neck cl in a fluid and air tight manner for instance by any adhesive means. It is obvious that instead of using adhesive means it is also possible to connect the neck of the tube tightly with the neck (I by providing annular pieces of cork, rubber or the like, more particularly, if the cliameter of the neck of the tube is not fully adapted to the diameter of the containers neck d. A closure device comprising the parts 0, f and g is located in the tube 1) independently arranged thereof. 0 is a ring, the

part f extends from the ring 0 to the packing plate 9. The packing plate 9 may be constructed of rubber or any other elastic or easily formable material and is suitably made of a larger diameter than the lower end of the glass tube, so that in spite of the rubber plate being somewhat downwardly deflected when put into position it may yet'fit close to the walls of the tube 12 and ensure an absolutely fluid-tight closure.

The manner of operation is as follows: The container a into which the tube 5 is not yet arranged is charged in the ordinary manner with the desired liquid, for example glue, however not up to the full height. After the tube 2) has been provided with the rubber The neck of the glass tube may also plate g which has to fit :fluidtight A within thc lower end it of the tube bathe latter one is introduced into the container a not completely. filled, the air escapes at (Z and the fluid is risingin "the-container in the same proportion co as-the volume of the tube b occupiesspace. As -the volume of the tube remains always the same, it is possible-to mark the container= at :a predetermined placeup to which the container-must be charged in order to be almost 6:" fullyfilled upafter the tube has been intro ducedi If the neck of'the tube lies close to the-neck of the container the air tig'ht 'connection is effected by. adhesive which maybe readily 'dissolvable if desired. If there -isa 7i)- distance between-the neck of the tube and the containers neck a packing ring or'the' like 'madeof rubb'er or similar material is inserted. Thewholedevice may then be closed at cllby a coverportion adapted to the coni 7 5 cal "form of the container andsuitably made of a material which: is readily drying up.: The part 70 may then be covered by a mark, label or trade mark of the respective manufacturing firm. The container can therefore only be opened after the closure 70 with the trade mark has been destroyed. By this manner the genuineness of the contents may be warranted.

The present invention olfers the following remarkable advantages:

The manufacture of the container a is very simple and inexpensive, and yet the container may be stable and durable. The inner tube-like part b may be constructed of quite thin and cheap glass as it is not subjected to damages from outside, and may be adapted to any desired container by inserting corresponding corks or rubber rings or the like. The parts 9, f and a forming a unit may also be produced in the simplest and most inexpensive manner, the part 9 beingmade in such a manner as to ensure an absolutely tight closure at about the level of the constant depth of the liquid so that while in transport 1 the contents will not in any position of the container enter the tube b. The closure 70 may Warrant the genuineness of the contents. After the vessel has been emptied it is only necessary to put it into warm water, which will allow the neck of the tube 7) to be removed from the part d of the container 0: by dissolvingthe adhesive. If the tight connection has been effected by annular packing members made of cork, rubber, or the like the tube may be removed of course without any treatment in warm water. The container is then recharged in the ordinary manner and made ready for transport.

The novelty of the present invention con sists in that a container with constant depth of the fluid is provided with a double closure so that when in transport the contents are prevented t'roln being spilled and of entering the tube; furthermore the second closure. portion is adapted to give a guarantee for the genuineness of the product. It is of great importance that according to the present application an airand fluid-tight closure is eflected at (Z so that on taking out the part 9 from the tube Z), the tube. will not be removed from the container at. It is therefore necessary when using packing members made of rubber or cork to arrange them more close than the part 9 in the lower end of the tube 6.

It is obvious that constructional or other changes may be introduced without depart ing from the scope of the present invention.

Having now particularly described and as ccrtained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is:

1. A container for fluid with automatically controlled uniform level of fluid, including a main container, a tube-like part having a conically shaped neck and being detachably arranged in said container and fitted air tight therewith by means of adhesive, said part having an upper opening and a lower opening approximately reaching the bottom of the main container.

2. A container for fluid as claimed in claim- 1 in which. said tube-like part is fitted air tight with the container by means of packing members.

3. A container for fluid as claimed in claim 1 including a closure portion arranged at the lower end of said tube-like part at about the level of the depth of the fluid, said closure portion being provided with means permit-- ting withdrawal of the closure portion.

4. A container as claimed in claim 1 comprising a closure member provided on the neck of the container and unremovable without destruction. 1

5. A container for fluid with automatically controlled uniform depth of fluid, including a main container having a tube-like part detachably arranged therein and fitted air-tight thereto, said part having an upper and a lower opening approximately reaching the bottom or said container, a closure member arranged at the lower end of said tube-like part at approximately the depth of the fluid, means permitting the removal of the closure portion, and a closure member fitted on the neck of the main container.

In testimony whereof I affix my signature.
